COOLING APPARATUS AND METHOD OF FABRICATION THEREOF WITH JET IMPINGEMENT STRUCTURE INTEGRALLY FORMED ON THERMALLY CONDUCTIVE PIN FINS
摘要:
A cooling apparatus and method of fabrication are provided for facilitating removal of heat from a heat-generating electronic device. The method of fabrication includes: bonding a plurality of thermally conductive pin fins to a surface to be cooled, each pin fin including a stem with a bulb structure on its distal end; depositing material onto the plurality of thermally conductive pin fins to integrally form a jet impingement structure with the pin fins, wherein the distal ends of the plurality of thermally conductive pin fins form part of the jet impingement structure; and controlling the depositing of material onto the distal ends of the pin fins to form a plurality of jet orifices in the jet impingement structure, with the depositing resulting in the plurality of jet orifices automatically self-aligning between the plurality of thermally conductive pin fins.
